Problems solved by technology

However, the manufacture of this type of formwork member is inconvenient, the production efficiency is low, it is not convenient for assembly line production, and the corresponding cost is high. The cast-in-place concrete hollow slab is in the evacuated part of the formwork member, its strength and stiffness are relatively poor, and its ability to withstand concentrated loads is relatively low. Therefore, it is urgent to develop a new type of cast-in-place concrete hollow slab.

Abstract

The in-situ cast hollow concrete slab includes reinforced concrete and shuttering members, which are coated inside the reinforced concrete and arranged at some interval with in-situ cast reinforced concrete ribs in between. Each of the shuttering members includes top plate, side walls and bottom enclose to constitute one hollow cavity. It features that at least one of the top plate, the side walls and the bottom has superposed layer combined with the base layer integrally, and that at least one of the side walls has transverse groove for in-situ casting reinforced concrete to constitute reinforcing rib. The present invention is suitable for use in various kinds of in-situ cast or pre-stressed reinforced concrete hollow floor slab, roof, wall, foundation slab and hollow bridge, especially hollow flat floor slab.

Description

(1) Technical field [0001] The invention relates to a cast-in-place concrete hollow slab. (2) Background technology [0002] At present, the cast-in-place concrete hollow slab is a widely used floor structure, and the lightweight permanent tire mold filled in it includes hollow tubes and cavity formwork components. For example, the patent No. ZL99249798.1, which the applicant applied for on November 29, 1999, is a utility model patent named "fiber-reinforced thin-walled member for reinforced concrete filling", which discloses a thin-walled formwork member, including an upper plate, The surrounding side walls, the lower bottom, and the upper plate, the surrounding side walls and the lower bottom form a polyhedral cavity. Another example is that the application number applied by the applicant on November 23, 2001 is 01140106.0, the publication number is CN1356442, and the name is called "a kind of cavity structure formwork for cast-in-place reinforced concrete floor slab" pat...
